Shallow world

Size: 5000 km - 10000 km

Usually found in a star's biozone. Has some atmosphere, but it is not very dense and generally considered unsuitable for life. This place will require gobs of habiforming if one is to make it friendly to life, and it probably won't be worth the effort when you're done. Rather than terraforming these worlds, the use of pressure domes and other life support devices is recommended. Some call them "Adaptable" worlds due to their somewhat neutral nature.
